Abstract
A linear roadway vehicle sensor for sensing vehicular traffic thereover includes a flexible carrier comprising an elongated flat elastomeric member having upper and lower surfaces and at least one groove in one of the surfaces. An elongated pressure sensor is carried in the one groove and a linear weight is distributed along and secured to the length of said flexible carrier. The weight has a weight per unit length which is sufficient to maintain said sensor on said roadway and substantially immune to lifting from the roadway because of air flow effects and turbulence caused by vehicles.
